 Community Right-to-Know and File Reviews

The Toxics Management Division (TMD) is the Certified Unified Program Agency (CUPA) for the City of Berkeley. TMD administers various CUPA and other environmental programs. TMD maintains documents related to the Emergency Planning and Community Right-To-Know Act (EPCRA). California has more stringent requirements than EPCRA and these laws are known as Hazardous Materials Business Plan (HMBP) per California Health & Safety Code, Division 20, Chapter 6.95. California Office of Emergency Services administers this program

The TMD maintains HMBP files for Berkeley facilities. In addition, the TMD maintains inspection and enforcement history for this and other CUPA programs and industrial stormwater pollution prevention program. Note: State law prohibits the TMD from releasing all HMBP documentation, including personal information, maps showing exact locations of hazardous materials and any trade secrets. Trade secrets may be released if no request for intervention is applied for by the facility.
